CASH-RE GISTER.

Specification of Letters Patent.

Patented July 4., 1911.

Application filed October 2, 1909. Serial No. 520,653.

To all whom it may concern:

Be it known that I, EDWARD J. VON PEIN, a citizen of the UnitedStates, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which I declare the following to be a full, clear, and exact description.

This invention relates to multiple totalizer cash registers, of the type which are provided with manipulative means for bringing any 'desired totalizer into operative relation with the totalizer actuators.

The manipulative means has heretofore coacted in such a way with machine looking devices that itvas necessary to operate the mani 'ml ative means before each operation of the machine,-for the purpose of compelling an operation of this manipulative means as a reminder to the operator so that he would not forget, to set the same and thereby possibly make the record in a wrong totalizer. Very often some one or more totalizers are operated much more frequently than others and under such circumstances it is desirable not to compel successive operations of the manipulative device when such a one of the tot-alizers is to be repeatedly in operative relation with the actuating mechanism.

The present invention relates to and has for its main object to provide adjustable means which may be arranged to act in such a way that upon any desired positions of the manipulative device it .Will be unnecessary to first operate the same in order to operate the machine.

With this and incidental objects in view the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and ,a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of the specification.

Of said drawings: Figure 1 is a left side elevation ofa cash register constructed according to this invention, but'with the multiple totalizers omitted. Fig. 2 is a transverse vertical section taken on the line 2-2 ofFig. 7. Fig. 3 is aright side elevation similar to Fig. 1, but showing some of the mechanism both in its normal position and in an intermediate position between its normal position and its fully moved position. Fig. 4 is a view similar to Fig. 3, but showing part of the mechanism both in its normal position and its fully moved position. Fig. 5 is a detail of the clerks initial bank of keys. Fig. (3 is a detail of the setting lever throwout mechanism. Fig. 7 is a rear elevation of the register partly broken away. Fig. 8 is a longitudinal section taken on the line 88 of Fig. 1.

The drawings show a pivoted lever serving as the manipulative device by which different totalizers may be brought into operative relation with the actuating mechanism. This lever *arries a segment gear which is adapted to mesh with a pinion which is fixed to and concentric with a reel for carrying the totahzers. The specific arrangement of the totahzers and their actuating nechanism and the means for controlling the actuating mechanism is fully illustrated and described in the patent to'l homas Carroll #703,639, granted July 1, 1902.

The setting lever is indicated in the drawings at 1, the segment gear above referred to which is part of the setting lever is indicated at 2, and the pivot oi the lever at 3. By rocking the lever 1 on its pivot different degrees the segment gear 2 causes the clerks totalizer reel to be rotated different degrees thereby bringing diii'erent totalizers into operative relation .with the actuating mechanism.

The lever 1 is alined in its diilerent settings by a plunger 4 which co-acts with. a plate 5 which is suitably curved for the purpose and which has notches 23 into which the plunger moves. The plunger 4 is spring pressed toward the plate 5 by a spring 6 (Fig. 2). The spring 6 normally draws a locking arm 7 domiwardly, this arm being fixed to a short. shaft 8 which shaft also carries one arm 9 of a pair of arms 9 and 10 which carry the plate 11 at the pivots l2 and 13. The arm 10 ispivoted to the frame of the machine on a pin 1-1. As the locking arm 7 is normally drawn downwardly, the plate 11 will be forced toward the alining plate 5. The plunger t is provided with a shoulder 15 extending across the front edge of the plate 11, and consequently is urged into engagement with the alining plate 5.

The plunger 4 is carried a bar 16 which is hungvfrom the lever-1 by links 17 and 18 and at 19 coacts with a downwardly extending lug 20 of a thumb grip 21 which is pivoted to the le er 1 on a pin.22. By forcing the thumb grip 21 toward the lever 1, the lug 20 engages the bar 16 thus moving the plunger 4 out of engagement with the alining bar 5. The lever 1 may then be set to any of the nine positions determined .by the nine'notches 23.

The lever 1 is rigid with a large segmentgear 24 whichmeshes with an intermediate gear 25 which in turn meshes with a pinion 26 fixed to an indicator drum 27. This drum is provided with nine characters representing the. different totalizers and the settings of the lever 1. The character which is brought opposite to a suitable sight opening in the cabinet at the rear of the register indicates which totalizer is in operative position. The drum 27, carries a gear-28 (Fig. 7) meshing with a pinion 29 on the shaft 30 which shaft carries a similar pinion 31 meshing with a gear 32 fast to a second indicator drum The drum 33 is similar to the -dru-m.27 butthe indicating characters are reversed on it for the purpose of indicating at the front of the register. By forcing the thumb grip 21 toward the lever 1, the locking arm 7 is forced into the cut 340i :1 disk 35'which is carried by the main drive shaft 36 of the machine.

' plunger 4 is in one of the notchesin the alining plate 5.

The machine is normally locked against operation regardless of the position of the locking arm 7 by an arm 37 (Figs. 1 and 2) which is normally in the path of a shoulder of a disk 38 which is carried by one member of a clutch 35). The co-acting member of theclutch is carried by a spiral gear .40. This gear meshes with a worm 41 which is carried by a shaft 42 fast to the armature-43 of a motor 44. The specific construction of the clutch 34 is described and illustrated in an application filed by C. F. Kettering and W. A. Chryst, Serial No. 394,187, filed Sep tember 123, 1907. As described in said application the disk 38 has a relative movement with respect to the member of the clutch which carries the disk for the purpose of actuating an arm 45 (Fig. 7) which at such time forces contacts 46 against a contact 47. These contacts are suitably connected to the source of electrical energy and to the motor 44 so that when the same are closed he spiral gear 40 will be. rotated.

This gear through the clutch 39 transmits energy from the motor to a stub shaft 48 (Figs. 7 and 8). which carries a bevel gear 49 meshing with a bevel gear 50 on the drive shaft 36. Because of this arrangement, when the arm 37 is rocked upwardly, thereby permitting the rotation of the shaft 48 and closing the contacts 46 and 47, the main drive shaft 36 will be rotated. The arrangement is such that the shaft 36 isper mitted to make one rotation only, upon each operation of the machine. The contacts 46 and 47. are automatically opened at the proper time by mechanism which is described in the said application. The manner of returning the arm 37 into the path of the disk 38 so that the drive shaft. 36 will be stopped at the completion of a rotation, will be stated in the ensuing description.

. The mechanism is arranged so that the locking arm 37 may be released by operation'of the thumb grip 21. To this end the arm 37 carries a roll 62 and surrounding this roll is the fork of an arm 61 mounted fast on a short shaft 60 to which a downwardly extending arm 59 is also fast. A link 55 connects the arm 59 to a second approximately parallel arm 57 fast on a shaft 58. A pair of toggle arms 53 and 54, connected by a pin 68, are provided, and toggle arm 53 is connected to link 55 by a pin 69 while tog le arm 54 is fast on a stub shaft 56 which 15 mounted in the machine frame. In the normal position of the parts as shown in Fig. 1 the line joinin pivots 56 and 69 of the toggle arms passes above the connecting pin 68 and therefore the locking arm 37 is held fast in locking position, but if the tog gle is broken by elevation of pin 68, thelocking arm may then be moved to releasing position by further rotation of the toggle arms, and in fact would be so moved by a spring 63 (Fig. 8) surrounding and fastened to the shaft 60, except for other parts yet to be mentioned.

In order to break the toggle by operation of thumb grip 21, an arm 51 is provided fast on shaft 8. Thus when the grip 21 is operated plunger 4 will be depressed, and will through plate 11 and arm'9 rock this shaft thereby raising the rear end of arm 51 to engage and move a roller 52 carried by toggle arm 53. As soon as the connecting pin 68-passes above the line between pivot pins 69 and 56 thespring 63 becomes effective and tends to move locking arm 37 to its releasing position. The action of the spring would, in this case, result in rocking the shaft 60 in the direction indicated by the in the path of the shoulder 72 of an arm 73 carried'by the shaft 58 which shaft also carries the arm 57 from which is hung the link 55. a

The key detent 71 may be actuated to carry the pin 70 inwardly clear of the shoulder 72, by any one of the keys 75 of a bank of special keys which are illustrated in Fig.

5. This bank of. special -keys controls elements of indicating mechanism and printv, machine until one of the special keys has been depressed. For this reason the key detent 71 which is moved upwardl upon the depression of a. key is" provide with the stop pin which before the detent is rocked upwardly is in the path of the shoulder 7 2 and consequently prevents the actuation of the spring 63. The detent 71 is loosely pivoted upon the shaft 3 and is provided opposite the keys with grooves 76 which are inclined to the path of movement of the keys. The shanks of the keys are provided with coacting inclined shoulders 77 and when any one key is depressed its shoulder -7 7 enters one of the grooves 76 causing the detent to be rocked upwardly so that the pin 70 will move into the slot 8 of the arm 72. "When the pin 70 is out of the ath of the shoulder 7 2, thespring 63 rock's tie stop arm 37 away from the 'disk 38 thereby causing the contac'ts 46 and 47 to be closed and the operation of the motor, which results in the rotation of the drive shaft 36. When the pin 70 is clear of the shoulder 7 2 the shaft 60 under the action of the spring rocks to carry the stop arm 37, theforked arm 61 and the arm 59 from the position in which they are shown in full lines in Fig. 4 to the position in which they are shown in broken lines in the same figure. This movement of the arm 59 draws the link 55 rearwardly thus moving the members 53 and 54 of the toggle as indicated by the broken lines in Fig. 4. The

movement of the link '55 also rocks its carryingarm 57 and the shaft 74 causing the arm 7 3 which the shaft carries to rock upwardly, with the pin 70 in the inner end of the slot 78 in the arm 73.-

It will beapparent after examining the structure as indicated by the drawings and so far described -that in order to cause the machine to operate as-desired it is necessary to actuate the lever 1 before the special key is depressed. If it was possible to actuate the machine by first depressing the special key and then set'tine the lever 1, upon forcing the thumb grip toward the lever 1, the stop arm would swing causing the machine to operate. As this would happen before the lever could be moved to a new position means are provided which preventsthe operation of the machine unless the lever l is set before the special key is depressed, This means consists of a pawl 79 which is carried by the arm 73 and is normally in such posi- 'tion that it Will'protrude Over the slot 78 inthe lever 73 and therefore prevent the lever 73 from rocking upwardly as the pin 70 would then engage the surface 80 of the pawl. The pawl 79 is normally below the path of movement of the pin 70 when the detent is rocked backwardly upon the depression of one of the keys, and if a key is a depressed before the lever 1 is actuated the pin 70 will pass over the surface 80 of the pawl as the detent moves rearwardly. '1herefore if the lever l is operated after the depression of the key, the machine will not operate. 4

If the lever 1 is operated before the depression-of the special key, the initial movement of the arm 73 will cause'the tip 81 of the pawl 7).to come into the path of movement of the pin '70. Then upon the "depression of a special key the pawl is rocked out of the path. of the pin allowing the lever to rock its full distance upwardly thus permitting the operation of themachine. In such case the shoulders 72 and 82 rock in front of the pin 70 and roller 83 preventing the return of the detent 71 until the arm 73 is restored to its initial position. \Vhen the detent. is thus locked in its moved position it is impossible to return the depressed key and it is also impossible to depress another in the same bank as the uncut port-ions 8*} of the detent are then in the paths of the keys. The detent is drawn to its normal position after the return of the arm 7 3 by the spring 85. During the rocking of arm 73 the roller 83 relieves the pin 70 from friction and wear which otherwise would occur by the pin 70 rubbing against the shoulder 72. v 7

As the retaining of the detent 71 in its moved position depends upon the actuation of the arm 73, if a key 75 is depressed before 7 necessary to release the key and again depress it in order to rock the pawl out of etc ping relation with the pin 70. he link 55 carries a roll 86 which, it will .be seen by referring to Fig. 4, moves into engagement with the end 87 of the arm 51, upon the backward movement'of. the link 55 when the locking arm 37 is moved away from the disk 38. Because of the roll 86 being in the path of the arm 51 it is impossible to operate the lever 1 while the driving mechanism ofthe machine is in motion as the arm 51 is fixed to the shaft 8 which carries the arm 9 which is one of the carryingarms of the plate 11. 'The forward edge of this plate extends across the rear side of the lug 15. It is therefore impossible to move the plunger 4-out of enga ement with the alimng plate 5 except by orcing the plate 11 rearwardly and consequently rocking the arm 51 upwardly.

The drive shaft 36 carries a camming arm 88 which when the drive shaft nears its home position forces a roller 89 on the arm 54 of the toggle to its original position, thereby returning the arm 73 (Fig. 5) to its original position permitting the detent 71 to'return to normal position and so releasing the key, and also causing the return of the stop 37 into the cut away part of the disk 38 so as to engage the shoulder of the disk and stop the disk when it arrives at its home'position. The contacts 46 and 47 are also opened when the shaft 36 reaches its home position.

F mm the foregoing description it will be understood thatit is impossible to' operate the machine. except by first actuating the lever 1 and therefore actuating the toggle composed-of the'arms 53 and 54 so that the spring 63 may cause the locking arm 37 to a be moved-away from the disk- 38. The releasing mechanism thus far referred to is to be found in said Kettering and Chryst application and the description has been repeated herein merely for the purpose of making the operation of the parts clear, so that the present invention, which will next be described, may be readily understood. 4

At times certain totalizersare used much more frequently than others and for this reason when the lever is set to the position for adding upon such totalizers there is no need of requiring an operation of the lever 1 merely to call the operators attention to whether or not the correcttotalizer 'is in mesh. For the above reason adjustable means are provided which may be set so that upon certain positions of the lever 1 it will be unnecessary to first operate the same before operating the-machine. This means comprises a device for automatically returning the toggle arms 53 and 54 upwardly so that the pivot (38 will be above the plane passing through the centers of the shafts 56 and 69. The cam 88 on the drive shaft 36 as explained rocks the arms 53 and 54 downwardly at the completion of each operation.

The shaft 56 which carries the arm 54 has loosely pivoted thereon an arm 90 (Fig.6)

and a spring 91 is interposed between the arm 90 and 3, lug 92 on the arm 54. The arm 90 also has an extension 93 which engages the upper surface of the lug 92 for the purpose of preventing the spring 91 from rocking the arm 90 away from the arm 54 except to a limited extent. It may be seen-because of the spring connection between the arms 54 and 90, that when the arms 53 and 54 are rocked downwardly by the cam 88 that the arm 90 will also be rocked downwardly, but if the arm 90 is obstructed at this time, the spring 91 will be compressed and therefore when the cam 88 clears the roll 89, the arms 53 and 54 will return upwardly until the ivot pin 68 is slightly above the plane passing through the shafts-56' and 69. The upward movement of the arms 53 and 54 at this timeis of course limited by the pin 70 of the key detent of the special bank, but-when the'toggle composed of the arms53'and 54 is in such position, in order to .operatethe machine it is by spring 91.

'In order to obstruct the movement of the I arm 90 only when the lever 1 is in certain predetermined positions, the segment gear 24 which is fitted to the lever 1 meshes with a pinion'94 on a short shaft 95 which shaft also carries a disk 96 provided with a number of holes 97 corresponding to the num ber of totalizers and suitable for receiving pins 98 (Fig. 6). If the lever 1 is set to such position that one of the pins 98 is op-.

posite the-lower end .99 of the arm 90, then r each time the machine is operated with the .pin in this position, when the cam 88 en-.

gages the roller'89, the arm 90. will engage the pin causing the spring 91 to be compressed. Then when the cam 88 clears the roll 89, the spring 91 will force the arms 53 and 54 into such position that an operation of the lever 1 will not be required again to operate the machine, but the machine may be released by depression of any key 75 of the Special-bank. The addition of this simple but effective mechanism lends to quickness of operationof the particular totalizers which are most *used and as seen,- the parts may be adjusted as desired so that any-particular 'totalizer position will notneed' an operation of the setting lever.

The invention has been shown in CO1111&C

tion with an electrically operated cash register,-but clearly none ofthe electrical features are at all concerned, and the invention is equally advantageous in other types of mechanism. The locking arm 37 has, as shown, functions of closing a circuit and permitting a clutching operation, but these functions are entirely aside and separable from its function of locking the machine, which latter is the only function it has in relation to the present invention. Clearly, whether the machine is driven by motor or by any connected mechanism or by hand,

would require no change in the releasing mechanism of the machine, and it is therefore to be understood that the invention herein is not to be limited to any particular style of driving mechanism, except as definitely limited in certain of the claims.

From the .foregoing description it 'will be evident that in the usual operation of the machine the main driving mechanism is nor mally locked by a means which is controlled by two separate manipulative devices, herein shown as a lever and an of a group of keys, and that therefore ad ustment of two devices is necessary to permit release of the driving mechanism. By the provision of an adjustable device, control of the locking means by one manipulative device is destroyed and by the further provision of" manually shiftable elements, namely, pins, the lever positions in which such control is destroyed may be regulated as desired.

In the operation of the improved machine, assuming the lever 1 adjusted so that a pin 98 is in position to coiiperate with arm 90, the straightening of the toggle by cam 88 will tension spring 91 and after cam 88 passes roller 89, the spring 91. will expand and break the toggle, leaving the machine at the end of the o )eration, with lever 73 engaging pin ot the key detent, wherefore a mere depression of a special'key will completely release the machine.

While the form of mechanism herein shown and described is admirably. adapted to fulfil the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms all coming within the scope of 'the claims which follow.
